> Subject: [PATCH v3] app/testpmd: send failure logs to stderr
> 
> Running with stdout suppressed or redirected for further processing
> is very confusing in the case of errors. Fix it by logging errors and
> warnings to stderr.
> 
> Since lines with log messages are touched anyway concatenate split
> format strings to make it easier to search using grep.
> 
> Fix indent of format string arguments.

> v3:
>  - fix typo in the patch description
>  - fix applicable coding style issues reported by patchwork
> 
> v2:
>  - switch from printf() to fpritnf(stderr, ...) in more cases
>  - do not inherit acks from the previous version since the patch is
>    much bigger
>  - fix style in few cases (TAB vs spaces, missing space separtor etc)
>  - still don't use TESTPMD_LOG() since the patch does not add new logs.
>    Also switching to TESTPMD_LOG() will add "testpmd: " prefix to log
>    messages and it is a real change and could be a pain for automation.
